The Files library starts here. A user's every download, clip and upload now
lands in a source folder made per origin (YouTube, Plex clips, uploads, one per
other site), decided once in downloads/folders.py at every place a job is made.
How long a file stays moves from the shared asset to the user's job: stamped
from its folder when it is done, never for a file the user keeps. The GC warns
each user once, then takes the expired file out of their library; the cache cap
never evicts a kept file, and an evicted one leaves every holder's library.
The media mount is /files now (FILES_ROOT, FILES_HOST_PATH, volume
siftlode_files); docs/self-hosting.md says how to carry an old volume over.
Migration 0102 places every existing job and carries each done file's expiry
over from its asset.
safe_abs_path takes a missing path and answers None, which drops one baselined
type error.
yt-dlp's `max_filesize` only stops a plain HTTP file that announces its size: YouTube's fragmented
formats never meet it — measured on localdev, a 718 MB download ran to the end with 1 MB left and
put its owner four times over the cap. The download now re-reads what is left once its file is made
(after the phone-safe pass) and refuses one larger than that as the owner's refusal; an editor clip,
which nothing checked, is held the same way, as a player clip already was.
